• Your 2 basic visual regression testing options

  Can you spot the visual bug on Netflix (as of August 2019, at https://devices.netflix.com/de/)? No wonder, there is a trend to visual regression testing of websites. Most current approaches to that problem are pixel based, meaning that they compare screenshots of the pages pixel-by-pixel. Instead, deep visual regression testing considers the CSS attributes of all elements, giving you unique advantages.Pixel-comparison based visual regression testingWhen you see that Netflix has a simple visual bug on the German version of their website for over two months now (as of August 2019, visit https://devices.netflix.com/de/), the trend towards visual regression testing of websites is understandable. This approach guards you from unexpected changes (for which writing assertions is impossible) and is much more complete than assertion-based testing. Most current approaches today are pixel based, meaning that they compare screenshots of the pages pixel-by-pixel. This makes a lot of sense: The first version of a pure pixel-diffing tool is easy to implement. It works for any browser, app or other situation, as long as a screenshot can be retrieved. It gives instant results. However, there are also some downsides to pixel-based visual regression testing: Similar changes cannot easily be recognized: e.g. if the header or footer of the site changes, this affects all tests. You usually get a lot of false positives, as even a small change can result in many elements changing e.g. position. Filtering these false positives is tricky, because it can result in either too many false positives (irrelevant changes being reported) or false negatives (important[…]

• Influence Equals Impact

  ”That’s VANITY, isn’t it?” a friend asked ”What’s the point to playing that social media game? Why would you take pics of yourself doing workshops? Or even do a vlog?””It’s 2019. Internet is everywhere. Influence equals impact” I replied.Your domain makes no difference. The value of your results is not just about the results you produce.It all boils down to the impact your results make on the people you serve. Are others willing to change their thinking, decisions or actions based on what you deliver?To create impact, you first need the skill. That’s obvious. Without skill, all the rest is pointless. Great results that create value to the people you serve are the precondition for everything else.Second, you need style. Nobody likes to work with an annoying smart ass even though they might have great results. It’s the how you deliver your results that matters. Do you see yourself as the El Hefe of a Michelin restaurant or a clerk at the junk food joint?Finally you need the status. Who are you when you deliver these results? Are you just a random passerby or are you a total guru of your field? Regardless of your title on the business card, are you a professional who commands respect in the minds of your clients, colleagues and bosses? Do you have social reference?It’s true that some might call it vanity; I call it professional reputation. The influence that you gather over time equals the impact your results later make!Would today be a great to day to start that[…]
